COMMENT: HF conditions stayed mostly at normal levels in Australian 
region with some periods of small MUF enhancements as well as 
period of small MUF depressions in the Northern parts of the 
region. Periods of Sporadic E blanketing were also evident. Mostly 
normal HF conditions may be expected in the region for the next 
three days (17 to 19 January) with some possibility of minor 
MUF depressions as the solar activity is expected to stay at 
very low levels during this period, which may result in the weakening 
of ionising radiation.
